    • Provided is a method of controlling a pointer, such as changing between a pointer mode for activating the pointer and a search key mode for deactivating the pointer, in a mobile terminal having a pointing device. The method of controlling a pointer includes detecting movement input by the pointing device; identifying whether the detected movement satisfies a condition of changing a display mode; if the detected movement satisfies a condition of changing a display mode, displaying the pointer by changing the current display mode to a pointer mode; identifying whether a specific key is input; and if the specific key is input, hiding the pointer by changing the current display mode to a search key mode. Additionally, if elapsed time measured after displaying the pointer exceeds a predetermined value, the display mode of the mobile terminal may automatically be changed to a search key mode.
    • 提供了一种控制指针的方法,诸如在具有指示设备的移动终端中改变用于激活指针的指针模式和用于停用指针的搜索键模式。 控制指针的方法包括检测由指示设备输入的移动; 识别检测到的移动是否满足改变显示模式的条件; 如果检测到的移动满足改变显示模式的条件,则通过将当前显示模式改变为指针模式来显示指针; 识别是否输入了特定的键; 并且如果输入了特定的键,则通过将当前显示模式改变为搜索键模式来隐藏指针。 此外,如果在显示指针之后测量的经过时间超过预定值,则移动终端的显示模式可以自动地改变为搜索关键模式。

    • A portable terminal and a user interface control method thereof are provided. In the terminal and method, patterns of a subject image captured by a camera are recognized and analyzed. First and second images changed according to motion (movement, holding away from or drawing close to a user) of the portable terminal are captured by the camera module. Patterns of the first and second images are recognized. The motion of the portable terminal is analyzed based on the recognized patterns. Control commands corresponding to the analyzed motion are selected. A function corresponding to the selected control command is performed. The portable terminal can be intuitively and simply used as its motion is directly applied to user interface control. User interface can be controlled without an additional part, using a camera installed to the portable terminal. Also, the present invention can resolve the problems caused when the conventional navigation key is operated.
    • 提供了便携式终端及其用户界面控制方法。 在终端和方法中,识别和分析由相机拍摄的被摄体图像的图案。 根据移动终端的移动(移动,远离或靠近用户)移动的第一和第二图像由相机模块捕获。 识别第一和第二图像的图案。 基于识别的模式来分析便携式终端的运动。 选择与分析运动对应的控制命令。 执行与所选择的控制命令相对应的功能。 便携式终端可以直观且简单地使用,因为其运动直接应用于用户界面控制。 可以使用安装在便携式终端上的摄像机,无需额外的部分来控制用户界面。 此外,本发明可以解决当传统导航键操作时引起的问题。
